Troubleshooting - TMC Aquarium V2Pure 50 Installations- Und Bedienungsanleitung

USEFUL TIP: An increase in the pressure reading on the pressure gauge indicates that the
flow restrictor/manual flush valve (18) is blocked and needs cleaning or flushing through
(see 2 in 'maintenance' above).
USEFUL TIP: A V
installed in-line on the RO system to measure and provide a highly accurate 'real-time'
display of total dissolved solids levels in the water, before and after going through the
V Pure RO membrane. This will detect any elevated TDS levels within the pure water
2
exiting the RO membrane indicating that the membrane is no longer operating at an
optimum level and needs to flushed or replaced (replacement RO membrane order code 5857).
USEFUL TIP: For optimum performance, and as an approximate guideline, we would
recommend that the RO membrane is replaced when the TDS level of the pure water
exiting the RO system reaches a maximum level of 10% of the feedwater (mains water).
For example if the TDS level of the feedwater (mains water) is 250ppm we would
recommend that the RO membrane is replaced when the TDS level of the pure water
reaches a maximum of 25ppm.

TROUBLESHOOTING

Problem: Reject water flow rate is too high.
1. Possible Cause: The flow restrictor/manual flush valve has not been correctly and
sufficiently closed.
Solution: Check and close the flow restrictor/manual flush valve accordingly.
2. Possible Cause: The flow restrictor/manual flush valve has a limited life span and may need
replacing.
Solution: Check the flow restrictor/manual flush valve and replace accordingly.
Problem: Reject water flow rate is very low or has stopped.
1. Possible Cause: RO membrane has become dirty and clogged and needs flushing or
replacing.
Solution: Check and manually flush the RO membrane and/or replace accordingly.
2. Possible Cause: The flow restrictor/manual flush valve has become blocked or faulty.
Solution: Manually flush the RO membrane to dislodge any blockage in the flow
restrictor/manual flush valve.
Solution: Replace flow restrictor/manual flush valve accordingly.
3. Possible Cause: There may be a kink in the RO tubing
Solution: Check the RO tubing and rectify any kinks accordingly
4. Possible Cause: A leak may have occurred somewhere in the installation.
Solution: Check for leaks and rectify accordingly.
5. Possible Cause: The mains water pressure may have dropped.
Solution: Check with your water supplier and install a booster pump if required.
6. Possible Cause: Ambient temperature may have dropped.
Solution: If necessary move the RO system to a location with a higher ambient
temperature.
Problem: Pure water flow rate is very high but there is very little reject water.
1. Possible Cause: The RO membrane has not been correctly and properly installed in the RO
membrane housing.
Solution: Check that the RO membrane has been installed correctly and that the tip of the
RO membrane has been correctly located in the recess inside the end of the RO
membrane housing.
